I have a customize B4860 board, there is no NOR flash.
There is one spansion spi flash and one MT29F4G08ABBDAH4 nand flash which is same with B4860QDS board. I'm using SDK-1.6, and use the u-boot config of B4860QDS_NAND_config to compile the u-boot. Final I got the u-boot-with-spl-pbl.bin image. Using codewarrior to write the uboot to the first block of nand flash. Then I switch the hw rcw_souce with 1_0000_01nn (for nn, I tried 00, 11, 01, 10, none of them work), seems the B4860 can't bootup. Anything wrong?
Anybody know the exact procedure to boot from NAND/SPI flash for B4860?
